It seems that .gcno files are no longer generated by
-fprofile-generate since GCC 4.4:
fraise% cat tst.c
int main (void)
{
return 0;
}
fraise% ls -l tst*
-rw-r--r-- 1 vlefevre users 32 2014-10-10 10:26:36 tst.c
fraise% gcc-4.3 tst.c -o tst -fprofile-generate
fraise% ls -l tst*
-rwxr-xr-x 1 vlefevre users 17612 2014-10-10 10:36:16 tst
-rw-r--r-- 1 vlefevre users 32 2014-10-10 10:26:36 tst.c
-rw-r--r-- 1 vlefevre users 160 2014-10-10 10:36:16 tst.gcno
fraise% rm tst.gcno
fraise% gcc-4.4 tst.c -o tst -fprofile-generate
fraise% ls -l tst*
-rwxr-xr-x 1 vlefevre users 17428 2014-10-10 10:36:27 tst
-rw-r--r-- 1 vlefevre users 32 2014-10-10 10:26:36 tst.c
fraise%
Is this change documented? I couldn't find anything related on:
http://www.gnu.org/software/gcc/gcc-4.4/changes.html
I'm just wondering...
I found that because it made an old script of mine fail when
cleaning up temporary files (problem solved by replacing "rm"
by "rm -f").
